Check out the most frequently asked question we receive for PSI Audio
No. All PSI Audio monitors are fully analogue. Precise driver design, cabinet tuning and individual factory calibration achieve the frequency and phase response, without relying on digital processing. This ensures consistent behaviour with no latency and no DSP artifacts.
PSI focuses on phase accuracy, linear frequency response and natural translation. Technologies such as CPR and AOI control driver behaviour in real time, resulting in stable imaging, clear midrange detail and mixes that translate reliably across other systems.
– Small rooms or broadcast: A14 M
– Compact nearfield mixing: A17 M
– Medium rooms / nearfield to compact midfield: A21 M
– Medium to larger rooms / detailed spatial work: A23 M
– Full range midfield / mastering / main monitor: A25 M
If you are unsure, GET IN TOUCH and we can advise based on your room dimensions and listening position.
Yes, provided placement is appropriate. PSI monitors are designed to maintain phase and tonal stability at lower listening levels, which is helpful in smaller spaces. However, basic acoustic treatment is still recommended for best results.
Yes. PSI offers matching subs designed to integrate seamlessly with their monitors without introducing phase smear. The A125-M and A225-M are the most common pairing options depending on room size.
You do not need to calibrate the monitors yourself. Technicians measure and calibrate each unit individually at the factory. Correct placement and listening distance are more important than any post-installation adjustment.
Yes, PSI monitors suit mastering work thanks to their controlled imaging, wide bandwidth and low listening fatigue. Their natural and uncoloured response makes them suitable for critical decision-making.
